At BMW, 3D Printing can transform Automotive Production

News from the 3D printing industry | 12 November 2021

Several technologies are transforming automotive production: smart data, lightweight construction, electrified powertrains, and 3D Printing! At the Rapid + TCT trade show, the German automaker underlines the development of Additive Manufacturing in the automotive sector. This technology can help manufacturers achieve economies of scale if material costs are low enough.

We believe that additive manufacturing might change the way that we could produce our cars or components in the future in a dramatic way“, Dominik Rietzel, BMW Group’s head of additive manufacturing in the non-metals division.

BMW has been developing prototyping for decades and uses Additive Manufacturing to produce foam prototype parts for dashboards, for example. Each engineer can generate prototypes of parts, which can be personalized to improve the assembly process.

Pursuing its motivation to increase its usage of 3D printing technologies, BMW is also developing its own 3D printing manufacturing process levels to have a generic approach and developed its own 3D printed components.

However, BMW wants to share this knowledge with the community “so that everybody can really improve their processes and supply us with parts in the future.” In this way, BMW has strong partnerships with HP Inc., EOS GmbH and wishes also to work closely with technological start-ups.

According to the BMW Group’s head of additive manufacturing in the non-metal division, 3D printing changes not only the way the company produces but also the way they builds their business model.

The launch of the Mini Yours Customized of BMW is a good example. Customers can change and choose diverse components that are 3D printed. This kind of customization is unusual in the automotive industry. For this project, the automated production of BMW can manufacture 504 parts per week on 2 M2 Carbon Printers.

The automotive company still wants to improve its future usage of Additive Manufacturing and has defined 4 main topics to focus on for 3D printing within the global organization, “functional safeguarding for the approval process, individualization for all the different products offered, series production only where it makes sense, and spare parts production where it is needed.”.

In conclusion, to go further in Additive Manufacturing, the car manufacturer still has to identify technological development, improve and develop materials to expand 3D printing manufacturing and transform its business model.
